Wife has an Ioniq 9, and she shared her digital key with me via Google Wallet. Look into that as an option for next time, I'd assume Apple has a similar implementation.

That said, the digital key is much more finicky/failure prone than my Tesla's implementation, and has a backup keycard I keep in my wallet (but have never had to use). Generally, rebooting the phone fixes it for some amount of time, until it stops working again with no indication until I try to unlock her car.
